Decades of manufacturing losses and population declines have left Cleveland with lots of empty warehouses and open spaces. But a growing number of creative Clevelanders spot opportunity in these places. One turned a sprawling warehouse into an indoor mountain bike track. A staffer at a struggling downtown mall is turning it into an urban greenhouse. And an artist is helping revitalize a tough inner-city neighborhood with his acclaimed papermaking studio. Experts say it's projects like these, not big convention centers and casinos, that will turn around former manufacturing cities, and Cleveland is helping lead the way.
